(2) Reading method of cable beam diagram

① Read the circuit principle diagram. The principle diagram of the car electrical appliances is the basis of the car line drawing. First understand the principle of circuit principles, which can be easier to understand the working principles and characteristics of the entire vehicle circuit, which helps to quickly understand the car line diagram. Using wire beam diagrams, you can understand the electrical equipment connected by each part of the line beam.

② Find the position of the main component. On the car line drawing, the main component marks are relatively obvious, and it is generally not difficult to find. For example, the generator and battery of the power system; starting the system of the system; the front lights, light switches of the lighting system; ignition coils, electrical appliances of the ignition system; electric speakers of the speaker system. After finding the main components of the unit circuit you need to check, then the number of them with the physical object on the car can be found according to the color and whereabouts of the wires on the car line drawing to find the wires or other components you are looking for.

③ Understand the information provided by the circuit diagram. In the circuit diagram, each wire is marked with numbers (or numerals and letters combination codes), which represent the color and diameter of the wire. When reading the color and diameter of the wire, 33, 33A, 33B, 33C, 33E such as 33, 33A, 33B, 33C, and 33E will appear. It indicates that this is the wire of the same path. Among them, 33 is the basic main line. 33A is a branch of the 33 line. It is different from the letters A. 33B is another branch of the 33 line. Use letters B to distinguish.

3.2.4 Reading points for the location diagram of automobile parts

The location diagram of the automotive parts is similar to the car wire beam diagram, marking the installation position of the electronic control system sensor and a actuator on the car. The part of the parts and the wiring chart, the circuit diagram can be used to quickly locate the detailed location of the sensor, a actuator, the relay, the melting wire, etc. in the actual maintenance, and then combined with the footprint to more accurately and quickly position the fault element. Figure 3-2-3 shows the part of the headlight cleaning control system and the installation position of the firing wire and relay.
